1 Program Summary

XC Series PLCs differ from the controllers in that the signal and execution of the program

occur in the controller. In this chapter, we begin with the program forms, introduce the

main features, the supported two program languages etc.

1-1．Program Controller Features

1-2．Programming Language

1-3．Program Formats


1-1 Program Controller Features

XC series PLCs support two kinds of programming language; Instruction List and Ladder, the

two languages can convert to each other.

The program is encrypted to prevent unlawful copying or modification. When uploading the

encrypted program, you will be asked to input a password. This maintains the user’s

Copyright.

When the user program becomes too long, adding comments to the program and its soft

components may be necessary.

Adding offset appendix (like X3[D100], M10[D100], D0[D100]) behind coils, data registers can

realize indirect addressing. For example, when D100=9, X3[D100]=X14; M10[D100]=M19,

D0[D100]=D9

With enough basic instructions XC Series PLCs can fulfill basic sequential control; data

moving and comparing; arithmetic operation; logic control; data loop and shift etc.

XC Series PLCs also support special comparisons; high speed pulse; frequency testing;

precise time; PID control: position control etc. for interruption, high speed counter (HSC).

Rich Basic Functions


XC Series PLCs support C language function block. Users can call the edited function block

freely. This function reduces the program size greatly.

XC Series PLCs support “Stop when Power ON PLC” function. With this function, if there is a

serious problem whilst the PLC is running, this function will allow the system to stop all output

immediately.

XC series PLCs support many communication formats, for example, Modbus communication,

CAN-Bus communication and Free Format communication. Via a special network module

PLCs can also be connected to Ethernet or GPRS net.

1-2 Programming Language

1-2-1 Types of Language Available

XC Series PLCs support two types of program language:

Instruction list inputs in the form of “LD”, “AND”, “OUT” etc. This is the basic input form of the

programs, but it’s hard to read and understand;

E.g.: Step Instruction Soft Components

With sequential control signal and soft components, it is possible to draw the sequential control

graph on the program interface, this method is called “Ladder”. This method uses coil signs etc.

to represent sequential circuits, so it’s easier to understand the program. Meantime, it allows

monitoring of the PLC showing the circuit’s status.

E.g.:

X0 X2

Y5

Y5

1-2-2 Alternation

The above two methods can convert to ech other freely:

0 LD X000

1 OR Y005

2 ANI X002

3 OUT Y005

Instruction Ladder

Ladder List

Instruction List


1-3 Programming Formats

The above two program methods allow input in the corresponding interface separately,

however, in the ladder window, there is an instruction hint function, this improves the program

efficiency greatly.

Direct Input


Some of the functions, like PID anf high speed counters, have a faceplate wizard which help

guide the user when inputing the configuration and settings.

2 Soft Component’s Functions and Actions

In chapter 1, we briefly covered the program languages of XC Series PLCs. However, the

most important element to a program is the operands. These elements relate to the relays

and registers inside the controller. In this chapter, we will describe the functions and

methods of using these.

2-12．Program Principle


2-1 Summary of the Soft Components

There are many relays, timers and counters inside PLCs. They all have countless

NO (Normally ON) and NC (Normally Closed) contactors. Connecting these contactors with

the coils will make a sequential control circuit. Below, we will introduce these soft components

briefly;

Usage of the input relays

The input relays are used to accept the external ON/OFF signal, we use X to state.

Address Specify Principle

In each basic unit, specify the ID of input relay, output relay in the form of

X000~X007，X010~X017…,Y000~Y007，Y010~Y017… (octal form).

The expansion module’s ID obeys the principle of channel 1 starts from X100/Y100,

channel 2 starts from X200/Y200… 7 expansions can be connected in total.

Points to pay attention to when using:

For the input relay’s input filter, we use digital filter. Users can change the filter

parameters via relate settings.

PLCs are equipped with with more relays than are required for the input/output

points, these can be utilized as auxiliary relays, program as normal contactors/coils.

Usage of the output relays

Output relays are the interface of drive external loads, represent with sign Y;

Address Assignment Principle

In each basic unit，assign the ID of output relays in the form of Y000~Y007,

Y010~Y017… this octal format.

The ID of expansion obeys the principle of: channel 1 starts from Y100, channel 2

starts from Y200… 7 expansions could be connected totally.

Input Relay ( X )

Output Relay ( Y )


Usage of Auxiliary Relays

Auxiliary relays are equipped inside PLC, represent with the sign of M;

Address assignment principle

In basic units, assign the auxiliary address in decimal form.

Points to note:

This type of relay differs from the input/output relay, it can’t be used to take an

external load, it can only use in program.

A retentive relay can keep its ON/OFF status in case of PLC power OFF.

Usage of status relays

Used as relays in Ladder, represent with “S”


In basic units, assign the ID in decimal form.

Points to note:

If not used as operation number, they can be used as auxiliary relays, program as

normal contactors/coils. They can also be used as signal alarms, for external diagnosis.

Usage of the timers

Timers are used to calculate the time pulse like 1ms, 10ms, 100ms etc. when the set value is

reached, the output contactor acts, represent with “T”


In basic units, assign the timer’s ID in decimal form, but divide ID into several parts according

to the clock pulse, accumulate or not. Please refer to chapter 2-2 for details.

Time pulse

There are three specifications for the timer’s clock pulse: 1ms, 10ms, 100ms. If 10ms timer is

selected, then timing is carried out in 10ms pulses.

Accumulation/not accumulation

The times are divided into two modes: accumulation time means even the timer coil’s driver is

OFF, the timer will still keep the current value; while the not accumulation time means when

the count value reaches the set value, the output contact acts, the count value clears to 0.

Auxiliary Relays ( M )

Status Relays ( S )

Timer ( T )


To facilitate different application and purposes, we can divide the counters to different types as

detailed below:

For internal count (for general use/Power OFF retentive usage)

16 bits counter: for increment count, the count range is 1~32,767

32 bits counter: for increment count, the count range is 1~2,147,483,647

These counters can be used by PLC’s internal signal. The response speed is one

scan cycle or longer.

For High Speed Count (Power OFF retentive)

32 bits counter: for increment/decrement count, the count range is -2,147,483,648~

+2,147,483,647

(single phase increment count, single phase increment/decrement count, AB phase cont)

The counters are tied to specific digital input channels.

The high speed counter can count 80KHz frequency, it synchronizes with the PLC’s

scan cycle.

Use of Data Registers

Data Registers are used to store data, represented by “D”

Addressing Form

The data registers in XC Series PLCs are all 16 bits (the highest bit is the sign bit), by

combining two data registers together 32 bit operationcan be achieved (the highest bit is

the sign bit) data process.

Points to note:

As with other soft components, data registers also have common usage type and Power

OFF retentive type.

Counter ( C )

Data Register ( D )


Usage of FlashROM registers

FlashROM registers are used to store data soft components, represent with “FD”

Addressing Form

In basic units, FlashROM registers are addressed in decimal form.

Points to note:

Even if the battery power is OFF, this area can retain data. So this area is used to store

important parameters. FlashROM can write about 1,000,000 times, and it takes time at

every write. Too many write instructions can cause permanent damage of the FD

address.

In every type of data in PLC, B represents Binary, K represents Decimal, H represents

Hexadecimal. They are used to set timers and counters values, or operands of application

instructions.

FlashROM Register ( FD )

Constant ( B ) ( K ) ( H )


2-2 Structure of Soft Components

2-2-1 Memory Structure

There are many registers in XC Series PLCs. In addition to the common data registers D and

FlashROM registers, we can also make registers by combining bit soft components.

For common use, 16 bits

For common use, 32 bits (via combine two sequential 16 bits registers)

For power off retentive usage, the retentive zone can be modified

For special usage, occupied by the system, these are special function registers used by

the system

For offset usage (indirect specifies)

MOV D10[D0] D100M8000

M2

Y0[D0]

MOV K5 D0

M8002MOV K0 D0

Form: Dn[Dm]、Xn[Dm] 、Yn[Dm] 、Mn[Dm] etc.

In the above sample, if D0=0, then D100=D10, Y0 is ON.

If M2 turns from OFF to be ON, D0=5, then D100=D15, Y5 is ON.

Therein, D10[D0]=D[10+D0]，Y0[D0]=Y[0+D0]。

The word offset combined by bit soft components: DXn[Dm] represents DX[n+Dm]。

The soft components with offset, the offset can be represented by soft component D.

Data Register ( D )


For common usage, 16 bits, represent the current value of timer/counter;

For common usage, 32 bits, (via combine two sequential 16 bits registers)

To represent them, just use the letter+ID method, such as T10, C11.

E.g.

MOV D0T11M0

T11Y1

X0T11 K99

For power off retentive usage, 16 bits

For power off retentive usage, 16 bits, (via combine two sequential 16 bits registers)

For special usage, occupied by the system, these are special function registers used by

the system

For common usage, 16 bits,

For common usage, 32 bits, (via combine two sequential 16 bits registers)

Timer ( T )

FlashROM Register ( FD )

Expansion’s Internal Register


For common usage, 16 bits, (via combine two sequential 16 bits registers).

The soft components which can be combined to be words are: X, Y, M, S, T, C.

Format: add “D” in front of soft components, like DM10, represents a 16 bits data from

M10~M25.

Get 16 points from DXn, but not beyond the soft components range.

E.g.:

MOV K21 DY0M0

MOV K3 D0M1

MOV DX2[D0] D10M8000

When M0 changes from OFF to be ON, the value in the word which is combined by

Y0~Y17 equals 21, i.e. Y0, Y2, Y4 becomes to be ON

Bit Soft Components Combined Register


2-2-2 BitSoft Components’ Structure

Bit soft components structure is simple, the common ones are X, Y, M, S, T, C however, a bit of

a register can also represent:

Input Relay X, octal type

Output Relay Y, octal type

Auxiliary Relay M, S, decimal type

Auxiliary Relay T, C, decimal type, as the representative method is as with registers, we

need to clarify if it’s a word register or bit register according within the register.

Made up by register’s bit, support register D

Represent method: Dn.m (0≤m≤15): the Nr.m bit of Dn register

The represent method of word with offset: Dn[Dm].x

Bit of Word can’t compose to be word again;

E.g.:

D0.4Y0

D5[D1].4Y1

D0.4 means when the Nr.4 bit of D0 is 1, set Y0 ON .

D5[D1].4 means bit addressing with offset, if D1=5, then D5[D1]

Input Disposal

Before PLC executing the program, read every input terminal’s ON/OFF status of

PLC to the image area.

In the process of executing the program, if the input is changed, the content in the

input image area will not change. However, in the next scan cycle, the status of the

input will change.

Output Disposal

Once finished executing all the instructions, transfer the ON/OFF status of output Y

Number List


In PLC, auxiliary relays M are used frequently. This type of relay’s coil is same with the output

relay. They are driven by soft components in PLCs;

auxiliary relays M have countless normally ON/OFF contactors. They can be used freely, but

this type of contactors can’t drive external loads.

For common use

This type of auxiliary relays can be used only as normal auxiliary relays. i.e. if power

supply suddenly stops during running, the relays will disconnect.

Common usage relays can’t be used for power off retentive, but the zone can be

modified;

For Power Off Retentive Use

The auxiliary relays for power off retentive usage, if power is lost to the PLC, the

ON/OFF satus is retained;

Power off retentive zone can be modified by the user;

Power off retentive relays are usually used to retain memory of the status before

power is lost, when power is restored to the PLC, the current status will resume;

For Special Usage

Special relays refer some relays which are defined with special meanings or

functions, start from M8000.

There are two types of usages for special relays, one type is used to drive the coil,

the other type is used to the specified execution;

E.g.: M8002 is the initial pulse, activates only at the moment of start

M8033 is “all output disabled”

Special auxiliary relays can’t be used as a normal relay M;

The auxiliary relays for power off retentive usage, if power is lost to the PLC, the

ON/OFF satus is retained;

Power off retentive zone can be modified by the user;

The status relays also have countless “normally ON/OFF” contactors. So users can use

them freely in the program;

Status relays are very import in ladder programming; usually use them with

instruction “STL”. In the form on flow, this can make the program’s structure

Other values (floating point)

XC programmable controller can be precision floating point functions.

Binary floating-point floating-point operations, while monitoring the implementation of

decimal floating-point values.

XC Series programmable controllers can be utilized for different uses and

purposes, they use of five types of number system, each role and functions

are as follows:

Data

Processing


Constant K

K is the symbol that a decimal integer, such as K10, expressed in decimal 10. It is

used for the specified timer, counter settings, and application instructions and

number of operations.

Constant H

H is the hex number of symbols, such as H10, is the hex number 10. Mainly used to

specify the application instruction operand values.

Value of the PLC program processing, you must use a constant

K, H. Generally used to refer to decimal K, H refer to the

hexadecimal number, but the PLC input and output relays with

octal numbers.

Tag I is usually used in interruption, including external interruption, time interruption etc.

use with IRET (interruption return), EI (enable interruption), DI (disable interruption);

External interruption

Accepts input signal from the special input terminals, not effected by the scan

cycle. Activates the input signal, executes the interruption subroutine.

With external interruption, PLC can dispose the signal shorter than scan cycle;

so it can be used as essential priority disposal in sequence control, or used in

short time pulse control.

Time interruption

Execute the interruption subroutine at each specified interruption loop time.

Use this interruption in the control which requires it to be different with PLC’s

operation cycle.

Action order of input/output relays and response delay

Input disposal

Before PLC executing the program, read all the input terminal’s ON/OFF status of

PLC to the image area. In the process of executing the program, even the input

changed, the content in the input image area will not change. However, in the input

disposal of next scan cycle, read out the change.

Output disposal

Once finished executing all the instructions, transfer the ON/OFF status of output Y

image area to the output lock memory area. This will be the actual output of the PLC.

The contacts used for the PLC’s exterior output will act according to the device’s

response delay time.

When using this input/output format in a batch, the drive time and operation cycle of input

filter and output device will also appear as per the response delay.

Tag I


Not accept narrow input pulse signal

PLC’s input ON/OFF time should be longer than its loop time. E.g. if input filter’s response

delay 10ms, loop time is 10ms，then ON/OFF time needs 20 ms separately. So, up to 1，000/(20+20)=25Hz input pulse can’t be disposed. But, this condition could be improved when

use PLC’s special function and applied instructions.

As shown in the left map, please consider

the things of using the same coil Y003 at

many positions:

E.g. X001=ON，X002=OFF

At first, X001 is ON, its image area is ON,

output Y004 is also ON.

But, as input X002 is OFF, the image

area of Y003 is OFF.

So, the actual output is: Y003=OFF,

Y004= ON.

When executing dual output (use dual coil),

the back side act in prior.

original bus line.

MCS, MCR instructions should use in pair.

The bus line could be used nesting. Between the matched MCS, MCR

instructions use matched MCS, MCR instructions. The nest level

increase with the using of MCS instruction. The max nest level is 10.

When executing MCR instruction, go back to the upper bus line.

3-16 Programming Notes

1: Program’s executing sequence

The program control flow is processed from【From top to bottom】and【From left to right】

Sequencial control instructions also encode following this flow.

2: Calling outputs multiple times

See the below example on how to stop this occuring

There are other methods. E.g. jump instructions or step ladder. However, when use step ladder,

if the main program’s output coil is programmed, then the disposal method is the same with

dual coil, please note this.

Description


1. The data contained within the two source devices are combined and the total is stored in

the specified destination device. Each data’s highest bit is the sign bit, 0 stands for

positive, 1 stand for negative. All calculations are algebraic processed. (5+(-8)= -3).

2. If the result of a calculations is “0”, the “0’ flag acts. If the result exceeds 323,767(16 bits

limit) or 2,147,483,648 ( 32 bits limit), the carry flag acts. ( refer to the next page). If the

result exceeds -323,768 (16 bits limit) or -2,147,483,648 (32 bits limit ) , the borrow flag

acts (Refer to the next page).

3. When carry on 32 bits operation, word device’s 16 bits are assigned, the device follow

closely the preceding device’s ID will be the high bits. To avoid ID repetition, we

recommend you assign device’s ID to be even ID.

4. The same device may be used a source and a destination. If this is the case then the

result changes after every scan cycle. Please note this point.

Flag Name Function

M8020 Zero

ON：the calculate result is zero

OFF：the calculate result is not zero

M8021 Borrow

ON：the calculate result is over 32767(16bits) or 2147483647(32bits)

OFF：the calculate result is not over 32767(16bits) or 2147483647(32bits)

M8022 Carry

ON：the calculate result is over 32767(16bits) or 2147483647(32bits)

OFF：the calculate result is not over 32767(16bits) or 2147483647(32bits)

Related Flag


Instruction D(NUM ) Object data

Instruction D(NUM) Object data Object data

1：Flag after executing the instruction. Instructions without the direct flag will not display.

2： Source operand, its content won’t change after executing the instruction.

3： Destinate operand, its content changes with the execution of the instruction.

4：Tell the instruction’s basic action, using way, applied example, extend function, note items etc.

The assignment of the data

The data register of XC series PLC is a single word (16 bit) data

register, single word data only engross one data register which is

assigned by single word object instruction. The disposal bound is:

Dec. –327,68~327,67, Hex. 0000~FFFF.

D(NUM) Single word object instruction

Double word（32 bit）engrosses two data register, it’s composed by two consecutive data

registers, the first one is assigned by double word object instruction. The dispose bound is:

D(NUM+1) D(NUM) Double word object instruction

The denote way of 32 bits instruction

If an instruction can not only be 16 bits but also be 32 bits, then the denote method for

32 bits instruction is to add a “D” before 16 bits instruction.

E.g：ADD D0 D2 D4 denotes two 16 bits data adds；

Between FOR/NEXT, LDP.LDF instructions are effective for one time. Every time when

M0 turns from OFF to ON, and M1 turns from OFF to ON, [A] loop is executed 6 times.

Every time if M0 turns from OFF to ON and M3 is ON, [B] loop is executed 5×7=35 times.

If there are many loop times, the scan cycle will be prolonged. Monitor timer error may

occur, please note this.

If NEXT is before FOR, or no NEXT, or NEXT is behind FENG,END, or FOR and NEXT

3. The data contained within the two source devices are combined and the total is stored in the

specified destination device. Each data’s highest bit is the sign bit, 0 stands for positive、1

stands for negative. All calculations are algebraic processed.（5+（-8）=-3）

4. If the result of a calculation is “0”, the “0” flag acts. If the result exceeds 323，767（16 bits limit）or 2,147,483,647（32 bits limit）, the carry flag acts.（refer to the next page）. If the result

exceeds –323,768（16 bits limit）or –2,147,483,648（32 bits limit）, the borrow flag acts（Refer

to the next page。

5. When carry on 32 bits operation, word device’s low 16 bits are assigned, the device following

closely the preceding device’s ID will be the high bits. To avoid ID repetition, we recommend

you assign device’s ID to be even ID.

6. The same device may be used as a source and a destination. If this is the case then the result

changes after every scan cycle. Please note this point.

LSR and SHR is different, LSR add 0 in high bit when moving, SHR all bits are moved.

< Logic shift left > < Logic shift right >

After once execution, the low bit is filled in 0, the final bit is stored in

carry flag.

LSL meaning and operation are the same as SHL.

After once execution, the high bit is same with the bit before shifting,

the final bit is stored in carry flag。

5-1 Functions Summary

XC series PLCs have an HSC (High Speed Counter) function which is independent of the

scan cycle. By choosing different counters, the high speed input signals can be tested with

detect sensors and rotary encoders. The highest testing frequency can reach 80KHz.


5-2 HSC Mode

The XC Series’ high speed counter function has three count modes: Increment Mode,

Pulse + Direction Mode and AB phase Mode;

Under this mode, count and input the pulse signal, the count value increase at each pulse’s

rising edge;

Under this mode, the pulse signal and direction signal are inputted, the count value increases

or decreases with the direction signal’s status. When the count signal is OFF, the count input’s

rising edge carry on plus count; When the count signal is ON, the count input’s rising edge

carry on minus count;

Increment Mode

Pulse + Direction Mode


Under this mode, the HSC value increases or decreases according to two differential signals

(A phase and B phase). There are two frequyency modes available: 1-time frequency and

4-time frequency. The default count mode is 4-time mode.

1-time frequency and 4-time frequency modes are shown below:

1-time Frequency

4-time Frequency

AB Phase Mode


5-3 HSC Range

5-4 HSC Input Wiring

HSC’s count range is: K-2, 147, 483, 648 ~ K+2, 147, 483, 647. If the count value overflows

this range, then up flow or down flow appears;

For “up flow”, it means the count value jumps from K+2, 147, 483, 647 to be K-2, 147, 483, 648,

then continues to count; For “down flow”, it means the count value jumps from K-2, 147, 483,

648 to be K+2, 147, 483, 647 then continues to count.

For the counter’s pulse input wiring, things differ with different PLC models and counter models;

several typical input wiring methods are shown below: (take XC3-48 as the example):


5-5 HSC Ports Assignment

Description of Letters:

U Dir A B

(OFF=increment, ON=decrement)

A phase input B phase input

Normally, X0 and X1 can accept 80KHz frequency under single phase mode and AB phase

mode. Other terminals can accept only 10KHz under single phase mode, 5KHz under AB

phase mode. X can use as normal input terminals when they are not used as high speed input.

M1 changes from OFF to be ON, reset C600, clears the count value


5-9 HSC Examples

Below, we take XC3-60 PLC as the example, to introduce HSC’s program form;

When M0 is ON, C600 starts the HSC with the OFF→ON of X000;

When comes the rising edge of M1, reset HSC C600

When normally ON coil M8000 is ON, set the value of C600, the set value is

K888888888, read the HSC value (DWORD) into data register D0 (DWORD).

If the value in C600 is smaller than value in D2, set the output coil Y0 ON; If the value

in C600 equals or be larger than value in D2, and smaller than value in D4, set the

output coil Y1 ON; If the value in C600 equals or be larger than value in D4, set the

output coil Y2 ON;

When comes the rising edge of M1, resets HSC C600 and stops counting.

When M4 is ON, C620 starts the HSC with the OFF→ON of X000; judge the count

direction according to the input X001 status (OFF or ON). If X001 is OFF, it’s increment

count; if X001 is ON, it’s decrement count;

When it reaches the rising edge of M5, it will reset HSC C620 and stop counting.

When the count value exceeds K3000, output coil Y2 is ON;

When comes the rising edge of M9, it resets HSC C630

When the rising edge of initial positive pulse coil M8002 comes, i.e. Each scan cycle

starts, HSC C630 reset and clear the count value.

When set coil M8000 ON, C630 starts to count, the count value is set to be K8888888。

If the count value is greater than K0 but smaller than K100, the output coil Y0 set ON; If

the count value is greater thanK100 but smaller than K200 时，the output coil Y1 set ON;

If the count value is greater thanK200, the output coilY2 set ON;

5-10 HSC Interruption

To XC series PLC, each HSC channels has 24 segments 32-bit pre-set value. When the

HSC difference value equals the correspond 24-segment pre-set value, then interruption

occurs according to the interruption tag;

To use this function, please use hardware V3.1c or above;

5-10-1 Instruction Description

(for Interruption program instructions, please refer chapter 5-10-4)

LD M0 //HSC activate condition M0 (interruption count condition)

OUT C600 K20000 D4000 //HSC value and set the start ID of 24-segment

LDP M1 //activate condition reset

RST C600 //HSC and 24-segment reset (interruption reset)

As shown in the above graph, data register D4000 is the start ID of 24-segment pre-set value

area. As a back-up, save each pre-set value in DWORD form. Please pay attention when

using HSC:

If certain pre-set value is 0, it means count interruption stops at this segment;

Set the interruption pre-set value but not write the correspond interruption program is

not allowed;

24-segment interruption of HSC occurs in order. I.e. If the first segment interruption

doesn't happen, then the second segment interruption will not happen;

24-segment pre-set value can be specified to be relative value or absolute value.

Meantime, users can specify the set value to be loop or not. But the loop mode can't be

used together with absolute value.

E.g.: 24-segment pre-set value of counter C600 correspond with the interruption pointer:

I1001、I1002、I1003、…I1024.

Increment Mode Pulse + Direction Mode AB Phase Mode

E.g. 1, the current value is C630 is 0, the first preset value is 10000, the preset value in

segment 2 is －5000, and the preset value in segment 3 is 20000. When counting begins: if the counter's current value is 10000, the first interruption I2501 will

be generated. When counting begins: if the counter's current value is 5000, the first interruption I2502 will be

generated. When counting begings: if the counter's current value is 25000, the first interruption I2503 will

be generated. See graph below:


C600 I1001~I1024

C602 I1101~I1124

C604 I1201~I1224

C606 I1301~I1324

C608 I1401~I1424

C610 I1501~I1524

C612 I1601~I1624

C624 I2201~I2224

C626 I2301~I2324

C628 I2401~I2424

HSC 24-segment pre-set value is the difference value, the count value

equals the counter's current value plus the preset value, self-generating

the interruption. N interruption tags correspond with N interruption preset

values. The (N+1) preset value is 0; Define the preset value

C600= K5000+K20000=K25000

C600= K10000+（K 5000）=K5000

C600= K0+K10000=K10000

K0 K10000 K-5000 K20000

I2501

I2502

I2503


E.g. 2, the current value is C630 is 10000, the first preset value is 10000, the preset value in

segment 2 is 5000, the preset value in segment 3 is 20000.

When count begins, if the counter's current value is 20000, this generates first interruption at

I2501;

5-10-3 Loop Mode of HSC Interruption

Mode 1: Unicycle (normal mode)

Not happen after HSC interruption ends. The conditions below can re-start the

interruption:

(1) reset the HSC

(2) Reboot the HSC activate condition

Mode 2: Continuous loop

Restart after HSC interruption ends. This mode is especially suitable for the following

application:

(7) continuous back-forth movement

(8) Generate cycle interruption according to the defined pulse

With setting the special auxiliary relays, users can set the HSC interruption to be unicycle

mode or continuous loop mode. The loop mode is only suitable with the relative count. The

detailed assignment is show below:

1: Concept of Step Frequency

2、frequency jump in segment pulse output

3: Dual pulse output is invalid

D0PLSR D100 Y0M0

D200PLSR D1000 Y0M1

In one main program, users can’t write two or more pulse output instructions with one

output port Y;

Therefore the sample below is wrong;

During ACC/DEC, each step time is 5ms, this time is fixed and not changeable.

The minimum step frequency (each step’s rising/falling time) is 10Hz. If the frequency is

lower than 10Hz, calculate as 10Hz; the maximum step frequency is 15Hz. If the

frequency is larger than 15Hz, calculate as 15Hz.

In case of frequency larger than 200Hz, please make sure each segment’s pulse

number no less than 10, if the set value is less than 10, send as 200Hz.

When outputting the segmented pulse, if the current segment’s pulse has been set out,

while meantime it doesn’t reach the highest frequency, then from the current segment to

the next pulse output segment, pulse jump appears, see graph above;


6-5 Sample Programs

E.g.2: follow function

In this sample, the pulse frequency from Y0 equals with the frequency tested from X003. If

the frequency tested from X003 changes, the pulse frequency from Y0 changes;

E.g.1: Stop at certain length

With instruction [PLSR] and [PLSNEXT], realize this “stop at certain length” function;

Take the sample program as the example, set

two segments pulse output in D0, D1 and D2，D3, with the same frequency value; In second

segment pulse output, set pulse number D3

as the output pulse number after receive M1

7-1 Summary

XC2-PLC, XC3-PLC, XC5-PLC main units can fulfill your requirements for communication

and networking. They not only support simple networks (Modbus protocol, Free

Communication protocol), but also support complicated networks.

XC2-PLC, XC3-PLC, XC5-PLC offer communication accessthat enables communication

with peripheral devices (such as printers, instruments etc.) that have their own

communication protocol.

XC2-PLC, XC3-PLC, XC5-PLC all support Modbus protocol and Free protocol however,

the XC5-PLC also supports CAN-Bus functions.

7-1-1 COM Port

There are 2 COM ports (Port1、Port2) on XC3 Series PLC basic units, while there are 3

COM ports on XC5 Series PLC main units. In addition to the same COM ports (COM1、COM2),

they have also CAN COM port.

COM 1 (Port1) is the program port, it can be used to download the program and connect

with the other devices. The parameters (baud rate, data bit etc.) of this COM port are fixed,

can’t be re-set.

COM 2 (Port2) is communication port, it can be used to download a program and connect

with the other devices. The parameters (baud rate, data bit etc.) of this COM port can be re-set

via software.

Via BD cards, XC Series PLCs can accommodate other COM ports. These COM ports

can be RS232 and RS485.

For the RS485 COM port, A is “+” signal、B is “-“ signal.

The A, B terminals (RS485) on XC Series PLCs come from COM2, so, you cannot connect a

device to the COM2 plug socket and also to the A & B terminals.

3: CAN COM port:

CAN port can be used to realize CAN-Bus communication. The pin terminals are “CAN+”,

“CAN-“

7-2 Modbus Communication

7-2-1 Function

XC Series PLCs support both Modbus master and Modbus slave.

MASTER FORMAT: When PLC is set to be master, PLC sends request to other slave devices

via Modbus instructions, other devices respond to the master unit.

SLAVE FORMAT: when PLC is set to be slave, it can only communicate with master devices.

The default status of XC-PLC is Modbus slave.

7-4 CAN-Bus Format

7-4-1 Brief Introduction of CAN-Bus

XC5 Series PLCs support CAN-Bus functions. Below we will give some basic concept on

CAN-Bus;

CAN (Controller Area Network) belongs to the industrial area bus category. Compared with

common communication bus, CAN-Bus data communication has performance of outstanding

dependability, real time ability and flexibility.

CAN controller works under multi-master format. In the network, each node can send data to

the bus according to the bus visit priority. These characters enable each node in the CAN-Bus

network to have stronger data communication real time performance, and easy to construct a

redundant structure, improving the system’s dependability and flexibility.

In CAN-Bus networks, any node can initiatively send message at any time to any other node,

no master and no slave. Enabling flexible communication; it’s easy to compose multi-device

backup system, distributing format monitor, control system. To fulfill different real time

requirements, the nodes can be divided to be different priority levels. With non-destroy bus

arbitrament technology, when two nodes send message to the network at the same time, the

low level priority node intuitively stops data sending, while high level priority node can continue

transferring data without any influence. This gives functions of node to node, node to

multi-node, bureau broadcasting sending/receiving data. Each frame’s valid byte number is 8,

so the transfer time is short, the probability ratio is low.


7-4-2 External Wiring

CAN-Bus Communication Port: CAN＋、CAN－

The wiring among each node of CAN-Bus is shown in the following graph; at the two ends, add

120 ohm middle-terminal resistors.

7-4-3 CAN-Bus Network Form

There are two forms of CAN-Bus network: one is instructions communication format; the

other is internal protocol communication format. These two forms can work at the same

time

Instructions communication format

This format means, in the local PLC program, via CAN-Bus instructions, execute bit or

word reading/writing with the specified remote PLC.

Internal protocol communication format

This format means, via setting of special register, via configure table format, realize allude

with each other among PLC’s certain soft component’s space. In this way, realize PLC

source sharing in CAN-Bus network.

basic units, including: call the instructions, set the parameters, items to note, sample

programs etc.

8-1 Brief Introduction of the Functions

PID instructions and auto-tune functions are added into XC Series PLC basic units (Version

3.0 and above). Via auto-tune method, users can achive the best sampling time and PID

parameters and improve the control precision.

The previous versions cannot support PID function on basic units unless they extend with

analog modules or BD cards. PID instruction has brought many facilities to the users.

1. The output can be data form D and on-off quantity Y, user can choose them freely when

programming.

2. Via auto-tune, users can achive the best sampling time and PID parameters and improve

the control precision.

3. User can choose positive or negative movement via software setting. The former is used in

heating control; the later is used in cooling control.

4. PID control separates the basic units with the expansions; this improves the flexibility of this

function.

S3~ S3+ 43 will be occupied by this instruction, do not use them as the common data

registers.

This instruction executes with each sampling time interval.

To the operation result D, the data registers are used to store PID output values; the

output points are used to output the occupy ratio in the form of ON/OFF.

PID control rules are shown as below:

e(t) = r (t ) –c ( t ) (1-1)

u(t) = Kp [ e ( t ) + 1/Ti∫e(t)dt + TD de(t)/dt] (1-2)

Here, e(t) is warp, r(t) is the given value, c(t) is the actual output value, u(t) is the control

value;

In function (1-2), Kp is the proportion coefficient, Ti is the integration time coefficient, and

TD is the differential time coefficient.

The result of the operation:

5. Analog output: MV= digital form of u (t), the default range is 0 ~ 4095.

6. Digital output: Y=T*[MV/PID output upper limit]. Y is the output’s activation time within the

control cycle. T is the control cycle, equals to the sampling time. PID output upper limit

default value is 4095.

8-3-2 Parameters Description

Movement Direction:

Positive movement: the output value MV will increase with the increasing of the detected

value PV, usually used for cooling control.

Negative movement: the output value MV will decrease with the increasing of the

detected value PV, usually used for heating control.

Mode Setting

Common Mode:

The parameter’s register zone is from S3 to S3+43, S3 to S3+11 and needs to be set by

users. S3+12 to S3+43+12 are occupied by the system and are not available to users.

Advanced Mode:

The parameter’s register zone is from S3 to S3+43, S3 to (S3+11) and (S3+40) to (S3+43)

need to be set by users. (S3+12) to (S3+39) are occupied by the system and are not

availableto users.

Sample Time [S3]

The system samples the current value according to certain time interval and compare

them with the output value. This time interval is the sample time T. There is no

requirement for T during AD output. T should be larger than one PLC scan period during

port output. T value should be chosen among 100~1000 times of PLC scan periods.

PID Operation Zone [S3+6]

PID control is entirely opened at the beginning and close to the target value with the

highest speed (the defaulted value is 4095), when it entered into the PID computation

range, parameters Kp, Ti, TD will be effective.

See graph below:

D 1 ·

If the target value is 100, PID operation zone is 10, then the real PID’s operation zone is from

90 to 110.


8-4 Auto-tune Mode

Death Region [S3+7]

Within this region the PID value will not vary. This stops the system from making small

changes which will imbalance the system.

D 2·

Suppose: we set the death region value to be 10. Then in the above graph, the difference is

only 2 comparing the current value with the last value. The PID control will not change value.

The difference is 13 (more than death region 10) comparing the current value with the next

value, this difference value is larger than control death region value, the PID control will start to

vary.


If users do not know how to set the PID parameters, they can choose auto-tune mode which

can find the optimal control parameters (sampling time, proportion gain Kp, integral time Ti,

differential time TD) automatically.

I. Auto-tune mode is suitable for these objectives: temperature, pressure; but is not

suitable for liquid level and flow.

II. Users can set the sampling cycle to be 0 at the beginning of the auto-tune process

then modify the value manually in terms of practical needs after the auto-tune

process is completed.

III. Before selecting auto-tune, the system should be under the no-control steady state. If

the function is to ‘Take the temperature’ for example: the detected temperature

should be the same as the environment temperature.

To enter the auto-tune mode, please set bit7 of (S3+ 2) to be 1 and turn on PID working

condition. If bit8 of (S3+ 2) turns to 1, it means the auto-tune is successful.

PID auto-tune period value [S3+ 8]

Set this value in [S3+ 8] during auto-tune.

This value decides the auto-tune performance, in a general way, set this value to be the AD

result corresponding to one standard detected unit. The default value is 10. The suggested

setting range:

full-scale AD result × 0.3 ~ 1%.

This value does not normally need altering, however, if the system is interfered greatly by

outside, this value should be increased modestly to avoid wrong judgment for positive or

negative movement. If this value is too large, the PID control period (sampling time) set by the

auto-tune process will be too long.

※1: if users have no experience, please use the defaulted value 10, set PID sampling time ( control

period ) to be 0ms then start the auto-tune.

PID auto-tune overshooting permission setting [S3+ 9]

If set 0, overshooting is permitted, the system can study the optimal PID parameters all the

time. But in self-study process, detected value may be lower or higher than the target value,

safety factor should be considered here.

If set 1, overshooting is not permitted. For these objectives which have strict safety demand

such as pressure vessel, set [S3+ 9] to be 1 to prevent from detected value being seriously

over the target value. In this process, if [S3+ 2] bit8 changes from 0 to 1, it means the

auto-tune is successful and the optimal parameters are set; if [S3+ 2] is always 0 until [S3+ 2]

bit7 changes from 1 to 0, it means the auto-tune is completed but the parameters are not the

best and need to be modified by users.

Every adjustment percent of current target value at auto-tune process finishing transition


8-5 Advanced Mode

stage [S3+10]

This parameter is effective only when [S3+ 9] is 1.

If setting PID control after auto-tune, small range of overshooting may be occurred. It is better

to decrease this parameter to control the overshooting. But response delay may occur if this

value is too small. The defaulted value is 100% which means the parameter is not effective.

The recommended range is 50~80%.

Cutline Explanation: Current target value adjustment percent is 2/3 (S3 + 10 = 67%), the original temperature of the

system is 0 ºC, target temperature is 100 ºC, the current target temperature adjustment

situation is shown as below:

Next current target value = current target value + (final target value – current target value) ×

2/3;

So the changing sequence of current target is 66 ºC, 88 ºC, 96 ºC, 98 ºC, 99 ºC, 100 ºC.

The stay times of the current target value at auto-tune process finishing transition stage

[S3+11]

This parameter is valid only when [S3+9] is 1;

If entering into PID control directly after auto-tune, small range of overshoot may occur.

Overshoot can be prevented if increasing this parameter properly, but it will cause response

lag if this value is too large. The default value is 15 times. The recommended range is from 5 to

20.


8-6 Application Outlines

8-7 Example Program

Users can set some parameters in advanced mode in order to get the better effect of PID

control. Enter into the advanced mode, please set [S3+2] bit 15 to be 1, or set it in the

XCP Pro software.

Input Filter constant

It will smooth the sampling value. The default value is 0% which means no filter.

Differential Gain

The low pass filtering process will relax the sharp change of the output value. The default

value is 50%, the relaxing effect will be more obviously if increasing this value. Users do not

need to change it.

Upper-limit and lower-limit value

Users can choose the analog output range via setting this value.

Default value: lower- limit output= 0

Upper -limit= 4095

Under continuous output, the system whose effectability will die down with the change of

the feedback value can do self-study, such as temperature or pressure. It is not suitable

for flux or liquid level.

Under the condition of overshoot permission, the system will get the optimal PID

parameters from self-study.

Under the condition of overshoot not allowed, the PID parameters got from self-study is

up to the target value, it means that different target value will produce different PID

parameters which are not the optimal parameters of the system and for reference only.

If the self-study is not available, users can set the PID parameters according to practical

experience. Users need to modify the parameters when debugging. Below are some

experience values of the control system for your reference:

Temperature system:

P (%) 2000 ~ 6000, I (minutes) 3 ~ 10, D (minutes) 0.5 ~ 3

Flux system: P (%) 4000 ~ 10000, I (minutes) 0.1 ~ 1

Pressure system: P (%) 3000 ~ 7000, I (minutes) 0.4 ~ 3

Liquid level system: P (%) 2000 ~ 8000, I (minutes) 1 ~ 5

Example: Add D0 and D1 in the PLC’s registers, then assign the value to D2;

(1) In “Project” toolbar, new create a Function Block, here we name the Function Block as

ADD_2, then edit C language program;

(2) Click compile after edition

According to the information shown in the output blank, we can search and modify the

grammar error in C language program. Here we can see that in the program there is no “;” sign

behind W[2]=W[0]+W[1];

Compile the program again after modify the program. In the information list, we can confirm

that there is now no grammar error in the program.

The information list


(3) Write PLC program, assign value 10 and 20 into registers D0, D1 separately, then call

Function Block ADD_2, see graph below:

(4) Download program into PLC, run PLC and set M0.

(5) From Free Monitor in the toolbar, we can see that D2 changes to be 30, it means the

assignment is successful.

9-6 Example Program

Function: calculate CRC parity value via Function Block

CRC calculation rules:

(1) Set 16 bits register (CRC register) = FFFF H

(2) XOR (Exclusive OR) 8 bits information with the low byte of the 16 bits CRC register.

(3) Right shift 1 bit of CRC register, fill 0 in the highest bit.

(4) Check the right shifted value, if it is 0, save the new value from step3 into CRC register; if it

is not 0, XOR the CRC register value with A001 H and save the result into the CRC register.

(5) Repeat step3&4 until all the 8 bits have been calculated.

(6) Repeat step2~5, then calculate the next 8 bits information. Until all the information has

been calculated, the result will be the CRC parity code in CRC register.

Edit C language Function Block program, see graph below:


9-7 Application Points

Edit PLC ladder program,

D0: Parity data byte number;

D1~D5: Parity data’s content, see graph below:

Download to PLC, then RUN PLC, set M0, via Free Monitor, we can find that values in D6

and D7 are the highest and lowest bit of CRC parity value.

When uploading a PLC program which contains some Function Blocks, the Function

Blocks can’t be uploaded, there will be an error say: There is an unknown instruction;

In one Function Block file, you can write many subsidiary functions, can call each other;

Each Function Block files are independent, they can’t call its owned functions;

Function Block files can call C language library functions in form of floating, arithmetic like

sin, cos, tan etc.

10-1 BLOCK Basic Concept

10-1-1 BLOCK Summary Sequential function block, in short BLOCK, is a program block to realize certain functions. We

can treat the block as a special flow, in this special flow, all the programs run according to one

principle, i.e. sequential execution principle; this is how BLOCK differs from other programs.

BLOCK starts with SBLOCK, ends with SBLOCKE, the programmer writes programs between

them. If in one BLOCK there are many “send pulse” instructions (also same with other type of

instructions), then the pulse instructions will run according to the time order of the activate

conditions; the next pulse instruction runs only after the previous instruction finishes.

See a whole BLOCK structure below:

Communication

Inverter Config.

10-1-2 Reason to introduce BLOCK

How to write instructions to optimize the original pulse, communication in flows;

As in XCP Pro, we don’t support to run many pulse, communication instructions in one

flow, it’s troublesome to write the program. With BLOCK, we support writing many pulse,

communication instructions, all the instructions run accord to sequential principle;

10-2 Call the BLOCK

In one program, you can call many BLOCKs. Call BLOCK via XCP Pro. See method below:

10-2-1 Add a BLOCK

Open XCP Pro, in the left toolbar, find “Sequence Block”, right click it, you can see “Add

Sequence Block”. See graph below:

Click this command, see the configure interface below:


The above interface is used to edit one BLOCK, in that interface you can add many program

sections, modify and delete the correspond sections, including pulse, communication, motion

control etc; upwards/downwards is used to up/down shift the instructions in BLOCK.

Please note: in the left bottom there is a “inset” item, if you choose it, the “Add” button will

change to be “Insert:, see screenshot below:

The difference between “Add” and “Insert”:

Add: add the specified content at the end of BLOCK;

Insert: add the specified content at any place of BLOCK;

Click “Add”, you can see that the system lists all the instruction types you may use, including

instruction list, pulse configure, Modbus instruction, Wait instruction, inverter read/write, free

format communication; see screenshot below:


For example, add a “Pulse Item” in the BLOCK and set it:

Click OK, we can see that in the configure interface, the corresponding information also been

added, see screenshot below:


Click “OK”, in the Ladder interface, you can see the instructions section as below:

Meantime, in the left toolbar, you can see the new added block, see graph below:


10-2-2 Move the BLOCK

If you want to move the created BLOCK elsewhere, you should delete the original BLOCK

(choose all and delete), see graph below:

Then move the mouse to the required place, activate this place; right click the created BLOCK,

in the pop-up menu, choose “Add To Lad”, see graph below:

Here we can see that the BLOCK appears at the activate place, see graph below


10-2-3 Delete the BLOCK

If just delete the BLOCK called in the program, you can choose the BLOCK area and delete

(refer the previous method).

If you want to delete one BLOCK thoroughly, choose “Delete Sequence Block”. After this, you

can’t call it any more, the only method is to add it again; see graph below:

10-2-4 Modify the BLOCK


10-3 Edit the internal instructions in BLOCK

After adding the BLOCK, if you want to modify it totally, you just click the start and end

segments in the ladder window; if you just want to modify a certain program segment, you just

double-click the instruction. The two methods are shown below:

（A）Double click the start/end segment of BLOCK:

（B）Double click certain instruction:


10-3-1 Common Item

In order to add the programs to BLOCK freely, we enable the user to write instructions in form

of instruction list.

Open the edit interface, click “Add”, see graph below:

Click “Common Item”, a new interface will pop up, see below:

In the interface, user can add the required programs freely. The point to note is that, “Skip” is


used to control the run or not on the instructions. If not fill it in, it default to run; if choose “Skip”,

and fill in the control coil, then when the coil activates, the instructions will not be executed.

See below:

Click “OK”, in the ladder you can see program as shown below:

The M0 before “Instruction List” is the condition to run the instruction or not.

Note: In one BLOCK, user can add many program segments, each segment is controlled by

“SKIP”. If the condition is true, then skip to run the instruction; if the condition is false or vacant,

execute the instruction.

In the above graph, the instruction list is not shown in details, but you can add the comments

according to the program’s function. See below:

After adding the comment, BLOCK changes in the ladder, see graph below:


10-3-2 Pulse Configure

Open “Pulse Config” interface with the same method, see below:

In this configure interface, you can set pulse output form, single or 24 segments, opposite or

absolute. Write the other parameters in the corresponding blanks, like frequency, pulse,

acceleration and deceleration time, pulse number etc.

Add two sending pulse instruction into “BLOCK”, see below:

※1：In BLOCK, the pulse output instructions are both in 32 bits form;

10-3-3 Modbus Instruction


As before, open Modbus instructions configure interface, see below:

Modbus instructions configuration is easy, just choose “Modbus Item” from the draw down

menu, fill in the remote station Nr., COM Nr., local coil ID, coil Nr., the system will generate the

instruction automatically. See below:

10-3-4 Wait Instruction

Same asthe previous method, open Wait configure interface. Wait instruction is used to wait


the flag bit or time. There are two wait forms in the configure interface, one is the flg bit, the

other is timer. See the configure method as below:

（A）Flag

（B）Timer Wait

（C）See the result in the ladder

10-3-5 Frequency Inverter Configure This time is applied for PLCs with XINJE inverters. By changing this interface, user can


read/write the inverters. See below:

The interface includes four parts, they are: inverter station number, COM port number, control

inverter action, monitor inverter’s status, user define etc. Below we introduce the four parts one

by one:

（A）inverter’s station number and COM port

The station number is used to specify the inverter’s station number, the COM port is PLC’s

COM port, see the configuration below:

（B）Control Inverter’s Action

This item includes “write constant value” and “write from register”. “write constant value”


specify the inverter’s running manner directly; “write from register” decide the inverter’s

running manner according to register’s value:

The first form is very easy, choose the required operation directly, see graph below:

For the second form, we take an example to show: write D0 into inverter:

（C）Inverter Status Read Into


This is used to read inverter’s status. According to the object shown on interface, insert the

value into the specified register in PLC, see below:

（D）User Define

Set the inverter via user define mode, read from and write into inverter directly. The configure

interface is shown below:


Add a write instruction, see configuration below:

Add a read instruction:

See the result below:


10-3-6 Free Format Communication Add free format communication instructions in the block.

For example, select “send” instruction, first address set to D0, serial port is 2, 16 bits.

There are two methods to set the data. Const data is to set the value directly. Reg is to set

the value via register.


10-4 Running Form of the BLOCK

Change to check out tab, select the checking mode.

The communication parameters also need to be set. Click “serial port config”:

1: If there are many blocks, they run as the normal program. The block is running when the

condition is ON.

（A）the condition is normal ON, normal OFF coil


（B）the condition is rising or falling edge of pulse

When M1, M2, M3 is from OFF to ON, all these blocks will run once.

2: The instructions in the block run in sequence according to the scanning time. They run one

after another when the condition is ON.

Explanation:

A) When M2 is ON, block 1 is running.

B) All the instructions run in sequence in the block.

C) M3, M4, M5 are the sign of SKIP, when they are ON, this instruction will not run.

D) When M3 is OFF, if no other instructions use this Y0 pulse , DPLSR D0 D2 D4 Y0 will

run; if not, the DPLSR D0 D2 D4 Y0 will run after it is released by other instructions.

E) After “DPLSR D0 D2 D4 Y0” is over, check M4. If M4 is OFF, check “DPLSR D0 D2

D4 Y1”, if M4 is ON, check M5. If M5 is OFF, “inverter config” will run.

Start the precise time in precise time interruption;

Every precise timer has its own interruption tag, see table below:

When X000 changes from OFF to be ON, timer

T600 starts to time. When time accumulates to

100ms, set T600; meantime, generate an

interruption, the program jumps to interruption tag

I3001 and execute the subroutine.

When X000 changes from OFF to ON, move the current

precise time value into TD600 immediately, regardless of

the scan cycle;

When M000 changes from OFF to ON, execute STRS

instruction immediately, stop precise time and refresh the

count value in TD600. Regardless of the scan cycle;

Precious Time Interruption


XC Series PLCs are equipped with an interruption function. The interruption function includes

external interruption and time interruption. With the interruption function we can utilize some

special programs. This function is not effected by the scan cycle.

11-4-1 External Interruption

The input terminals X can be used to input external interruption. Each input terminal

corresponds with one external interruption. The input’s rising/falling edge can activate the

interruption. The interruption subroutine is written behind the main program (behind FEND).

After interruption generates, the main program stops running immediately, turn to run the

correspond subroutine. After subroutine running ends, continue to execute the main program.

If use EI instruction to allow interruption,

then when scanning the program, if

interruption input changes from OFF to be

ON, then execute subroutine①、②, return to

the original main program;

Interruption pointer (I****) should be behind

FEND instruction;

PLC is default to allow interruption

Within the main program’s execution cycle, if you need to handle a special program; or

during the sequential scanning, a special program needs to be executed at a certain

time, time interruption function is required. This function is not affected by PLC’s scan

cycle, every Nm, executes a time interruption subroutine.

Time interruption is defaulted in open status, time interruption subroutine is similar with

other interruption subroutine, it should be written behind the main program, starts with

I40xx, ends with IRET.

There are 10CH time interruptions. The represent method is I40**~I49** (“**” means time

interruption’s time, unit is ms. For example, I4010 means run one channel time interruption

every 10ms.

12 Program Application Samples

In this chapter, we make some samples about pulse output instruction, Modbus

communication instructions and free format communication instructions etc.

12-1．Pulse Output Application

12-2．Modbus Communication Application

12-3．Free Format Communication Application


12-1 Pulse Output Application

Example: below is the example program to send high/low pulse in turn

Each Parameter:

Stepping motor parameters: step angle= 1.8 degrees/step, scale=40, pulse number per rotate

is 8000

High frequency pulse: maximum frequency is 100KHz, total pulse number is 24000 (3 rotates)

Low frequency pulse: maximum frequency is 10KHz, total pulse number is 8000 (1 rotates)

DPLSR D200 D210 D220 Y0 //value in D200 is frequency、value in D210 is

pulse number、value is D220 is acceleration/deceleration time, send pulse via Y0;

Explanation:

When PLC changes from STOP to be RUN, M8002 gets a scan cycle;

set the high frequency pulse parameters into D200、D210,

set the acceleration/deceleration speed to D220,

set M0, the motor starts to run 3 rounds with high frequency.

Meantime M8170 sets; the motor runs 3 rounds and decelerate, stop, coil M8170 reset;

then reset M0, set M1, NOT M10;

set the low frequency pulse parameters into D200、D210;

the timer time lags 2sec, when time reaches, reset M1;

set M0, the motors starts to run 1 round with low frequency;

after this starts to run with high frequency.

Repeat this alternation time by time;


12-2 Modbus Communication Application

E.g.1: realize Modbus read/write among one master and three slaves

Operation: (1) write content in D10~D14 to D10~D14 of 2# slave;

(2) read D15~D19 of the slaves to D15~D19 of the mater; anyhow, write the first

five registers’ content to the slaves, the left five registers are used to store

the content from the slaves;

（3）3# 、4# slaves are similar;

Soft component’s comments:

D0: communication station number

D1: offset

M2: 2# communication error



M8137: COM2 communication error end signal

M8138: COM2 communication correct end signal

Ladder

S0: write the target station

S1: read the target station

S2: judge the communication status

S3: offset the communication ID

T200: communication interval 1

T201: communication interval 2

T202: self reset 1 of communication error

T203: self reset 2 of communication error


In PLC’s first scan cycle,

evaluate the “communication

station” to be 2;

Evaluate the “offset” to be 0

2# communication error reset



S0 starts, T202 counts 2S, which is the

communication wait time

When the communication wait time

reaches, no matter the communication

succeeds or not, T200 time 20ms, this

time is used start the next

When communication waiting time

reaches, no matter the communication

succeeded or not, T201 counts 20ms, this

time is used to start the next

T201 times reach, or on the

power up, execute the read

operation with the target stations

Open flow S2

Flow S2 is used to judge the

communication status. Failure

will set the correspond coil;

success will reset the

correspond coil;

If the station number is not larger than 4,

the station register add 1, the offset add

10

If the station number is larger than 4,

evaluate the station register 1; clear the

offset register

Open flow S0


Program Explanation:

When PLC turns from STOP to RUN, M8002 gets a scan cycle. S0 flow open, write the

master’s D10——D14 to slave 2# D10——D14. no matter the communication is success or

not, turn to S1 flow; check the previous communication written condition. After certain time

delay, continue to read D15~D19 data from 2#. After this reading entr S2 flow, check if the

communication is success. If failed, set M23, enter alarming. After finishing the communication

with 2#, enter S3, then flow S3 will judge with the station number. If the station number is less

than 1, the offset add 10; or else start from 2# again.

e.g. 2: Below is a sample of XC Series PLC with two XINJE inverters, they communicate via

Modbus communication, XC Series PLCs write the frequency to the two inverters;

set the first inverter’s station to be 1; set the second inverter’s station to be 2; store the

frequency’s set value in D1000 and D2000. execute the frequency setting order via COM

ports;

Program Description:

On the rising edge of M8012, write frequency to the first inverter; on the falling edge of M8012,

write frequency to the second inverter;


12-3 Free Format Communication Application

In this example, we use DH107/DH108 series instruments;

1、Interface Specifications

DH107/DH108 series instruments use asynchronous serial communication interface, the

interface level fits RS232C or RS485 standard. The data format is: 1 start bit, 8 data bits, no

parity, one/two stop bit. The baud rate can be 1200~19200bit/s.

2、Communication Instruction Format

DH107/108 instruments use Hex data form to represent each instruction code and data;

Read/write instructions:

Read: address code +52H (82) +the para.(to read) code +0+0+CRC parity code

Write: address code +43H（67）+ the para.(to write) code +low bytes of the wrote data +

high bytes of the wrote data +CRC parity code

The read instruction’s CRC parity code is: the para. (to read) code *256+82+ADDR

ADDR is instrument’s address para., the range is 0~100 (pay attention not to add 80H). CRC is

the remainder from the addition of the above data (binary 16bits integral). The reminder is 2

bytes, the high byte is behind the low byte;

The write instruction’s CRC parity code is: the para. (to write) code *256+67+ the para.

value (to write) +ADDR

The para. to write represents with 16 bits binary integral;

Regardless of whether it is write or read, the instrument should return data as shown below:

The test value PV+ given value SV+ output value MV and alarm status +read/write

parameters value +CRC parity code

Among in, PV、SV and the read parameters are all in integral form, each occupies two bytes,

MV occupies one byte, the value range is 0~220, alarm status occupies one byte, CRC parity

code occupies two bytes, totally 10 byes.

CRC parity code is the reminder from the result of PV+SV+ (alarm status *256+MV)+

para. value +ADDR;

(for details, please refer to AIBUS communication description)

3、Write the program

After power on the PLC, the PLC read the current temperature every 40ms. During this period,

the user can write the set temperature.

Data zone definition: buffer area of sending data D10~D19

buffer area of accepting data D20~D29


instruction’s station number: D30

read command’s value: D31=52 H

write command’s value: D32=43 H

parameter’s code: D33

temperature setting: D34

CRC parity code: D36

Temperature display: D200,D201

The send data form: 81H 81H 43H 00H c8H 00H 0cH 01H (current temperature display)

Communication parameters setting: baud rate: 9600, 8 data bits, 2 stop bits, no parity

Set FD8220=255; FD8221=5

( the hardware and software must be V2.4 or above)
